A la lumière de faits biologiques dûment confirmés, touchant à la transformation cellulaire maligne et, plus particulièrement, à la radiocancérogenèse, on discute les bases sur lesquelles sont fondées les valeurs des doses de rayonnements ionisants actuellement considérées comme admissibles. Cette mise en question entraîne de sérieuses conséquences sur des notions fondamentales, telle l'existence de seuils, sur les méthodes d'extrapolation des FF (fortes doses, forts débits) au ff (faibles doses, faibles débits), enfin sur la considération qu'on doit accorder aux fluctuations de la radiation naturelle.
Abstract
In the ligt of well-established biological facts concerning the malignant transformation of cells and, more particularly, radiation carcinogenesis, the bases on which the values of the doses of ionizing radiations presently permissible have been founded are discussed. This casts doubts on the serious consequences of such foundamental questions as that of thresholds, the methods of extrapolation from HH (high doses, high dose-rates) to ss (small doses, small dose-rates), and finally on the consideration which must be granted to the fluctuations of natural radiation.
